The Agents of the Great Outdoors are on a super-secret spy mission! Shhh! They're going undercover to find out if the noises animals make are their own way of talking to each other, and whoever finds the answer will get the Golden Badge of Honor. Ooooh! It's so golden and so badge-y and all at the same time. The Agents of the Great Outdoors are on the case! Time to find out if animals communicate!

It's a beautiful spring day when Daisy gets an urgent video chat from her best gardening pal, Petunia, who has moved to the city. Petunia has gotten herself into a quite a pickle. The Urban Gardening Club is coming to consider her for club membership in a month. Only trouble is, she doesn't have a garden, and she doesn't know how to grow one in the city. If she can't become a member of the Urban Gardening Club, she doesn't know what she'll do. Not to worry! No garden is impossible for Daisy and her pals! Time to build a city garden! Tally ho!

Daisy's whole garden isn't looking so good. The plants are all droopy and way smaller than last year. Daisy explains that the reason is because they are in a drought, which means it hasn't rained in a while. And since it hasn't rained, her rain barrel, which she uses to water her plants, is totally empty. Even other woodland creatures are thirsty and looking for water because of the drought. Man oh man! Nature Cat and the gang have to do something to help, but they can't make it rain! What they can do is learn to conserve water!

Nature Cat and his pals are assembled in Ye Olde Kingdom of the Backyard to play. The Knights of Nature! Huzzah! When Ronald sees their shiny Knights of Nature helmets, he's entranced and wants one of his own. But not so fast, Ronald! Nature Cat explains that in order to wear a helmet, Ronald must become a Knight of Nature by going on a quest, and his quest is to find a dragonfly! Huzzah!

Hal has been inside his doghouse all week trying to build a Squeak-a-saurus Rex, a model Tyrannosaurs Rex built completely out of squeak toys. It's gonna be fabuladocious! But every time he's about to be finished, the model breaks apart, making Hal very frustrated and tired. He'll never get his Squeak-a-saurus Rex finished!! Dr. Daisy has the remedy. A dose of nature should do the trick! It's time for Hal to take a break and go outside!

It's a crisp autumn day and Nature Cat and his pals are raking leaves in their backyard when a large creepy shadow suddenly covers them. Nature Cat looks up to see big bald birds swooping over their heads. What are those things? And what do they want? Ahhhh! The scary birds come down to introduce themselves as Tammy and Tobias. The gang learns that they're turkey vultures, and despite their intimidating appearance, they come in peace, man!

During band practice, some unexpected guests interrupt. Papa and Mama Vole (and all their young'uns) pop up to see if they can bunk with Hal. They're having a little problem at their burrow so they need to find shelter. Hal is happy to have the company at first, but when the voles start to take over and eat all his plants, it's time to ask the voles to leave. Easier said than done, as getting the voles back in their home sets off a chain reaction of other animal habitat problems!

Houston's cousin Nigel is coming to visit next week all the way from England. Nigel wants to join Houston on one of his famous nature adventures. Daisy suggests Houston take Nigel on The Tough Track Adventure, a nature obstacle course happening the day that Nigel arrives. But Houston has a problem he's never been on an actual nature adventure before. He only assists his friends with their nature needs using his computer. How can he get ready for a nature adventure in a week? Never fear! Nature Cat and the gang will help!
